Walking in the hills and chanced upon an exposure of early Devonian here (at least I think it is).
About 3 feet above the rock slab is a 2 foot thick formation bearing either trace fossils or nodules. They seem more like mineralized nodules to me.
For some reason, yesterday, perhaps due to intense morning light angle on the rock surface, I could just not get a good focus. Note the markings in the brownish trace or nodule. Nothing continuously longer than 4" found. Most exposures either broken or seeming to recede into the formation.
Thoughts please....
